Mortar Prism Molds and Prism Testing Accessories
This category collects the equipment used to cast, store and handle mortar prisms and test bars. Start from the specimen dimensions your method requires, then select the mold, compaction tool and storage arrangement for that geometry. Nominal size similarity does not make two prism products interchangeable.
Choose the Prism Mold by Specimen Size
Compare the listed prism molds by cavity dimensions and gang configuration: the 2 x 2 x 10in two-gang mold, the 1 x 1 x 10in single- and two-gang molds in bronze and stainless steel, the 3 x 3 x 10in single molds, and the 1 x 1 x 5in two-gang molds including the stainless steel version. Volume-change prisms in 1.6 x 1.6 x 6.3in three-gang and 4 x 4 x 10in single formats are also listed. Order the exact specimen size specified by your method.
Match the Compaction Equipment
Compare the rubber tamper, the ASTM wood tamper and the non-ASTM rubber-compound tamper, plus the listed tamping rods. Use the compaction tool the method prescribes for the mold type; an ASTM-designated tool and a non-ASTM alternative are not substitutes for each other.
Plan Storage with Bar Containers and Holders
For prism storage, compare the round mortar bar container and the round container with bar holder, and the containers for length-gauge testing. Match 5in and 10in mortar test bars and the stainless steel bar holder to the container arrangement. Where the method requires restraint, check the restraining cages in the matching bar size, along with gauge studs and the demolding device.
Supporting Equipment for Volume-Change Work
Vibrating tables with fast-action, general and cube clamps, plus the precision three-gang and 2in cube molds for vibrating tables, support specified compaction workflows. For length measurement of prisms, use the length comparators listed with the cement expansion testing equipment rather than substituting an unrelated gauge.
Grout Prism Supplies Are Listed Here Too
Grout prism kits, liners, spacer blocks, retainers and capping stands appear in this category for grout specimen work. Use them with the grout procedures in the grout testing category, not as direct substitutes for mortar prism molds.
Confirm the Order
Verify specimen dimensions, mold material, gang count, container capacity, bar size and fixture compatibility. Follow the applicable method and manufacturer instructions for casting, compaction, storage and measurement; this guide does not set prism dimensions or acceptance criteria.
